SELECT SUBSTR('&&STR',ROWNUM,1)
||DECODE(ROWNUM,1,SUBSTR('&&STR',2,LENGTH('&&STR')),LENGTH('&&STR'),' ',LPAD(' ',LENGTH('&STR')-2,' '))
||DECODE(ROWNUM,LENGTH('&&STR'),SUBSTR(REVERSE('&&STR'),2,LENGTH('&&STR')-2),' ')

How To Send E-Mail From PostgreSQL

AS $function$

import smtplib
sender = _from
receivers = receiver
message = ("From: %s\nTo: %s\nSubject: %s\n\n %s"
 % (_from,receiver,subject,send_message))

try:

  smtpObj = smtplib.SMTP(smtp,port)

Pgpool Configuration & Failback

I would like to share the pgpool configuration, and it's failback mechanism in this post.

Hope it will be helpful to you in creating pgpool and it's failback setup.

Pgpool Installation & Configuration

pgBucket - A new concurrent job scheduler

Hi All,

I'm so excited to announce about my first contribution tool for postgresql. I have been working with PostgreSQL from 2011 and I'm really impressed with such a nice database.

I started few projects in last 2 years like pgHawk[A beautiful report generator for Openwatch] , pgOwlt [CUI monitoring. It is still under development, incase you are interested to see what it is, attaching the image here for you ],


pgBucket [Which I'm gonna talk about] and learned a lot and lot about PostgreSQL/Linux internals.

Using pgBucket we can schedule jobs easily and we can also maintain them using it's CLI options. We can update/insert/delete jobs at online. And here is its architecture which gives you a basic idea about how it works.


Yeah, I know there are other good job schedulers available for PostgreSQL. I haven't tested them and not comparing them with this, as I implemented it in my way.
Features are: OS/DB jobsCron style sytaxOnline job modificationsRequired cli options
